I'm sorry about what you went through with this person. This statute requires prosecutors to prove intent on behalf of Microsoft; it also requires active concealment, intentional aid in avoiding arrest, or warning (or "harboring", which would require Microsoft to actually provide physical shelter and concealment). Presumably the arrest warrant you're talking about is public; disclosing the existence of a public document seems unlikely to be prosecutable.

I appreciate the rest of the details you've provided on the thread!
